Best ResponseYou've already chosen the best response.0Area of a circle is \[\large A=\pi \times r^{2}\] Right now we have the diameter, which is 28. To get the radius, we have to divide the diameter by 2. So \[\large \frac{28}{2}=r\] Once you get the r tell me and we'll plug it into the area of a circle formula :)

Best ResponseYou've already chosen the best response.0@Sachintha it looks like you combined the circumference formula and area formula together.

Best ResponseYou've already chosen the best response.0Right. And since we're using 22/7 for pi, it would look like this \[\large A=\frac{22}{7} \times 14^{2}\] The next step is to find 14^2

Best ResponseYou've already chosen the best response.0Yep that would be it, good job :). So now we are gonna multiply 196 by 22/7. Which will look like this \[\large A=\frac{22*196}{7}\] So our next step is to find 196*22

Best ResponseYou've already chosen the best response.0Right, good job. Now we have to divide 4312 by 7. Which will look like this \[\large A=\frac{4312}{7}\] This is gonna be our final step :)

Best ResponseYou've already chosen the best response.0Yep, that would be our answer, so \[\large A=616\] or more specifically \[\large A=616cm^{2}\]
